RT8125F/G  
High Efficiency Single Synchronous Buck PWM Controller  
General Description  
Features  
Richtek Mach ResponseTM Technology  
1% High Accuracy 0.8V Reference  
VCC Input Range : 4.5V to 13.2V  
VOUT Operating Range : 0.3V to 3.3V  
Power Stage Input Range : 1.5V to 24V  
Fixed Operating Frequency : 300kHz  
VIN Detection  
The RT8125F/GPWM controller provides high efficiency,  
excellent transient response, and highDC output accuracy  
needed for CPU core, I/O, and chipset RAM supplies in  
notebook computers.  
Richtek Mach ResponseTM technology is specifically  
designed for providing 100ns instant-onresponse to  
load transients while maintaining a relatively constant  
switching frequency.  
LG_OCSET for Current Limit  
PGOOD Indicator  
The RT8125F/Gachieves high efficiency at a reduced cost  
by eliminating the current sense resistor found in  
traditional current mode PWMs. Efficiency is further  
enhanced by its ability to drive very large synchronous  
rectifier MOSFETs. The Buck conversion allows this device  
to directly step down high voltage batteries at the highest  
possible efficiency. The RT8125F/Gprovides an 1% high  
accuracy 0.8V reference voltage with minimum 1mA  
source/sink current for high accuracy output application.  
Embedded Bootstrap Switch  
High Side Gate Driver Pull Low Resistor (10kΩ)  
Current Limit with Low Side Current Sense Scheme  
Enable Function with Internal Pull High Current  
OVP/UVP/OTP/Pre-OVP/Current Limit  
Shutdown Current <100μA  
RoHS Compliant and Halogen Free
